G...I disagree on this...
I prefer media Player 10...and I install 10 in XP every time I load XP...
I have 9 and 10...I have loaded MP-11 to XP several times and sound quality wasnt as good as it was in 10...I have tried going straight to 11 or over the top of 9 and over the top of 10 and it didnt matter...
11 seems to have issues...? not sure...I have one rig with XPpro and 11 that doesnt sound to bad...
XP-64 with MP-11 is just plain god awful...But....XP-64 with MP-10 sounds the best out of ANY XP set up I have...I dont know why....
Even on the NF3 rig with XPpro and XP-64 and Vista...
XP-64 with MP-10 has the best sound...which I find rather weird...but it does...
In MP-11 you need to make sure you go over the settings carefully...In alot of cases the SRS-WOW effects are ON by default...turn them OFF and it will sound better...
